I am trying to (slowly) rank for a very high competition keyword on my primary website (6 years work and counting). I am currently 15-19th place for the keyword (local UK) and want to get on page 1. I think it's something like 160k local monthly searches, might be more. At the moment I am building high quality links (paid for on a per link basis) as well as a few link exchanges. I know it's a bit task but I'm not in a rush as the site does very well anyway. The thing is I have had good success on other sites with services offered here, but I don't know how risky they are? So just wondering what services are safe to use on money sites and/or what are the best techniques.? Thanks.
